Description

  The present invention relates to a browsing policy determination apparatus that determines a browsing policy that is a limitation on browsing by a viewer for position information indicating the position of a user device.

  2. Description of the Related Art Conventionally, a portable terminal that can disclose the location of its own terminal to a partner terminal is known (for example, Patent Document 1 below).

JP 2009-296664 A

  The mobile terminal described in Patent Document 1 has a configuration in which, from the viewpoint of privacy protection, a public level that defines details of the location of the terminal to be disclosed is set by the user of the terminal for each location. . Then, the location of the terminal is disclosed to the counterpart terminal with details based on the disclosure level set for the location. As described above, in the mobile terminal described in Patent Document 1, it is necessary for the user to manually set the disclosure level for each location, which imposes a heavy burden on the user and greatly reduces user convenience.

  Therefore, the present invention has been made in view of such problems, and further reduces the burden on the user, and provides a browsing policy that is a restriction on browsing by the viewer with respect to position information indicating the position of the user device. It is an object of the present invention to provide a browsing policy determination device that can determine a browsing policy.

  In order to solve the above-described problem, the browsing policy determination apparatus according to the present invention determines a browsing policy, which is a limitation on browsing by a viewer, with respect to position information indicating the position of a user device, for each position. A position history storage unit for storing position history information indicating a history of the position of the user device, and browsing at a position included in the position history information based on the position history information stored by the position history storage unit Browsing policy determination means for determining a policy and outputting the determined browsing policy. With this configuration, the browsing policy is determined based on the position history information. That is, the browsing policy can be determined based on the history of the position of the user device without the user performing a special operation. That is, it is possible to further reduce the burden on the user and determine the browsing policy.

  The browsing policy determination device of the present invention further includes a base calculation unit that calculates a base indicating a position where the user device stays based on the position history information stored by the position history storage unit, and the browsing policy determination unit includes: The browsing policy at the base calculated by the base calculation means may be determined. By adopting such a configuration, it is possible to determine the browsing policy at the base indicating the position where the user device stays.

  The browsing policy determination device of the present invention further includes a specific site setting unit that sets a specific site indicating a specific position among the sites calculated by the site calculation unit, and the browsing policy determination unit is configured to browse at a single site. When determining the policy, the number of times the user equipment has moved from the specific base set by the specific base setting means to the one base without passing through the other base, and the other base from the one base to the specific base At least one of the number of times the user device has moved without going through the location is calculated based on the position history information stored by the position history storage means and the base calculated by the base calculation means. It is good also as determining the said browsing policy based on. With this configuration, the browsing policy is determined based on at least one of the number of times that the user device has moved directly from the specific base to the one base and the number of times that the user device has moved directly from the one base to the specific base. For example, when a specific base is a home, the location information of one base that has been moved frequently from the home and one base that has been moved directly to the home is equivalent to the user's daily behavior and is confidential. Therefore, there is a high possibility that there will be no problem for the user even if it is viewed. Therefore, for example, as the number of times increases, it is possible to determine a browsing policy that is more problematic for the user by deciding the browsing policy so as to loosen the restriction on browsing the position information of the user device at the one base. .

  Further, in the browsing policy determination device of the present invention, when the browsing policy determination unit determines the browsing policy at one site, the time when the user device stayed at the one site is stored by the position history storage unit. The browsing policy may be calculated based on the position history information and the browsing policy may be determined based on the calculated time. In general, it is highly possible that the location information of one base where the user device has stayed has a problem for the user even when viewed. Therefore, for example, by determining the browsing policy so as to loosen the restriction of browsing with respect to the position information of the user device at the one base as the time is longer, it is possible to determine a browsing policy that is more problematic for the user. .

  In the browsing policy determination device of the present invention, the position history storage means further stores browser position history information indicating the position history of the browser device carried by the viewer, and the browsing policy determination means stores the position history storage. Based on the position history information stored by the means and the browser position history information of the browser device carried by the viewer, the browsing policy for the viewer at the position included in the position history information may be determined. If such a configuration is adopted, since the browsing policy of the browser for the location information of the user device is determined based on the location history information of the user device and the viewer location history information of the browser device, for example, the user device And the browsing policy of the said viewer can be determined based on the similarity of a movement of the browser apparatus which a viewer carries.

  Further, in the browsing policy determination device of the present invention, the location indicating the location where the user device stayed and the location where the viewer device stayed based on the location history information and the viewer location history information stored by the location history storage means, respectively. Further comprising a base calculation means for calculating each of the viewer bases indicating the position, the browsing policy determination means, the position history information stored by the position history storage means and the viewer position history information of the viewer device carried by the viewer; Based on the base calculated by the base calculation means and the viewer base of the viewer device, a browsing policy for the viewer at the base may be determined. By adopting such a configuration, it is possible to determine the browsing policy of the viewer at the base indicating the position where the user device stays. In addition, since the browsing policy is determined based on the position history information of the user device and the browser position history information of the browser device, and the base of the user device and the viewer base of the browser device, for example, the user device And the browsing policy of the said browser can be determined based on the similarity of the movement regarding the base of the browser apparatus which a viewer carries.

  In the browsing policy determining apparatus of the present invention, the browsing policy determining means carries the user device and the one viewer at the one base when determining the browsing policy for the one viewer at the one base. The time when the browser device stayed together is the location history information stored by the location history storage means, the viewer location history information of the viewer device, the base calculated by the base calculation means, and the viewer base of the viewer device. And the browsing policy may be determined based on the calculated time. In general, the location information of one base where the user device and the browser device carried by the viewer stay together together has a high possibility that there is no problem for the user even if the location information is browsed by the viewer. Therefore, for example, the longer the time is, the more the browsing policy is determined for the user by deciding the browsing policy so as to loosen the browsing restrictions on the position information of the user device at the one base. can do.

  In the browsing policy determination device of the present invention, when the browsing policy determination means determines the browsing policy for one viewer at one base, the user device and the viewer device carried by the one viewer The location stored by the location history storage means the number of times the user device and the one viewer device have moved together from one site to another site from the other site. Calculate based on the history information, the browser location history information of the browser device, the base calculated by the base calculation means and the browser base of the browser device, and determine the browsing policy based on the calculated number of times It is good as well. Generally, the number of times the user device and the viewer device carried by the viewer have moved together from one site to another site, and the user device and the viewer device have moved together from the other site to the one site. The greater the number of times the user has performed the position information of the one base, the higher the possibility that the user will have no problem even if the position information is viewed by the viewer. Therefore, for example, by determining the browsing policy so as to loosen the restriction of browsing of the viewer with respect to the position information of the user device at the one base as the number of times increases, a browsing policy that is more problematic for the user is determined. can do.

  Further, in the browsing policy determining device of the present invention, the browsing policy determining means calculates a browsing tolerance indicating a browsing tolerance, determines a browsing policy based on the calculated browsing tolerance, and the determined browsing policy May be output based on the calculated browsing tolerance. By adopting such a configuration, for example, for a user, position information with a higher viewing allowance is displayed at a higher position, and position information with a lower viewing allowance is displayed at a lower position. Can be understood intuitively.

  According to the present invention, there is provided a browsing policy determination device that can further reduce a user's burden and can determine a browsing policy that is a limitation of browsing by a viewer for position information indicating the position of a user device. be able to.

  Hereinafter, embodiments of a browsing policy determination apparatus according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a server 1 that is a browsing policy determination apparatus according to the present embodiment. The server 1 is a device that allows a third party other than the user of the portable terminal 2 to view position information indicating the position of the user of the portable terminal 2 (the user who owns the portable terminal 2). The position information indicating the position of the user of the mobile terminal 2 is information indicating the location of the user such as where the user of the mobile terminal 2 is now. In the present embodiment, as a specific example of the position information, information indicating whether or not the user is at the position and information indicating whether or not the position is in the vicinity (for example, within a radius of 1 km from the position) are used. The third party is, for example, a user of another mobile terminal 2 that is different from the user of the mobile terminal 2. The server 1 may be a device that allows a third party other than the user of the mobile terminal 2 to browse the position information indicating the position of the mobile terminal 2 instead of the position information indicating the position of the user of the mobile terminal 2. . In this case, in the present embodiment, the “position of the user of the mobile terminal 2” is appropriately replaced with “the position of the mobile terminal 2”, and the “user” is appropriately replaced with “the mobile terminal 2”. Hereinafter, a user whose position information is browsed is called a person to be browsed, and a third party who browses position information is called a viewer.

  The server 1 further has a function of determining and outputting a browsing policy for the position information of the viewed person. The browsing policy is a restriction on browsing of location information by a viewer. The restriction of browsing is, for example, whether or not browsing is permitted, and if browsing is permitted, how much detail the position information (in the above-mentioned, whether or not the position is present, and around the position). Whether or not browsing is permitted. The server 1 allows the viewer to browse (publish) the location information of the browsed person based on the determined browsing policy.

  The server 1 determines a browsing policy for position information indicating the position of the person to be viewed for each position. Moreover, the server 1 determines the browsing policy with respect to the positional information which shows a to-be-viewed person's position for every browsing person and the said position. In the present embodiment, the two determination methods described above by the server 1 will be described.

  The portable terminal 2 is a device that is carried and used by a user (including a viewed person and a browsing person). Specifically, the mobile terminal 2 corresponds to a mobile phone, a smartphone, or the like. Note that the mobile terminal 2 may be a general device other than a mobile phone having a positioning function capable of positioning the position information of the device itself. The portable terminal 2 can communicate via a network N such as a mobile communication network, and can transmit and receive information to and from each other. As will be described later, the mobile terminal 2 requests the server 1 to browse the location information of the designated person to be browsed, and returns a result corresponding to the viewing policy determined by the server 1 as the response. Is displayed to the viewer who is the user of the terminal.

  As shown in FIG. 1, in the present embodiment, a mobile terminal 2 a (user device) and a mobile terminal 2 b (browser device) will be described as an example of the mobile terminal 2. The portable terminal 2a and the portable terminal 2b are collectively referred to as a portable terminal 2. In the present embodiment, the user of the mobile terminal 2b browses (trys to browse) the location information of the user of the mobile terminal 2a. That is, the user of the mobile terminal 2a is the person to be viewed, and the user of the mobile terminal 2b is the viewer.

  The portable terminal 2 has a positioning function for positioning a positioning point that is the position of the terminal itself, such as GPS (Global Positioning System). The portable terminal 2 transmits positioning information indicating the positioning point obtained by the positioning function to the server 1. The positioning information is information indicating latitude and longitude, for example. The user who owns the mobile terminal 2 is given a user ID that is information for specifying the user in advance, and the mobile terminal 2 transmits positioning information to the server 1 together with the user ID stored in advance. The positioning of the own terminal by the portable terminal 2 is continuously performed, for example, periodically (for example, every 10 minutes). The positioning information transmitted from the portable terminal 2 to the server 1 is grasped as position information related to the position measured on the server 1 side. For example, the mobile terminal 2 transmits the positioning information to the server 1 in association with the positioning time. Alternatively, the mobile terminal 2 transmits positioning information to the server 1 each time positioning is performed.

  The mobile terminal 2 includes hardware such as a CPU (Central Processing Unit), a memory, and a wireless communication module, like a normal mobile phone or smartphone.

  Subsequently, the function of the server 1 will be described. As shown in FIG. 1, the server 1 includes a storage unit 10 (position history storage unit), a positioning information reception unit 11, a base calculation unit 12 (base calculation unit, specific base setting unit), and a browsing policy determination unit 13 (browsing policy). Determining means), a browsing policy manual setting unit 14 and a browsing request processing unit 15.

  The server 1 is composed of hardware such as a CPU. FIG. 2 is a diagram illustrating an example of a hardware configuration of the server 1. As shown in FIG. 2, the server 1 shown in FIG. 1 physically includes a CPU 100, a RAM 101 and a ROM 102, which are main storage devices, an input / output device 103 such as a display, a communication module 104, an auxiliary storage device 105, and the like. It is configured as a computer system including.

  The functions of the functional blocks of the server 1 shown in FIG. 1 are configured such that predetermined computer software is loaded on hardware such as the CPU 100 and the RAM 101 shown in FIG. This is realized by operating the module 104 and the auxiliary storage device 105 and reading and writing data in the RAM 101.

  Hereinafter, each functional block of the server 1 shown in FIG. 1 will be described.

  The storage unit 10 is a storage unit that stores (stores) information necessary for processing in the server 1. The storage unit 10 is, for example, a database. The storage unit 10 stores user information related to the user of the mobile terminal 2 in the user information table. For example, the user information may be stored in advance by an administrator of the server 1 or may be stored based on information received from another device via a network. FIG. 3 is a diagram illustrating a table example of the user information table. As illustrated in FIG. 3, the user information table stores information in which a user ID, a group ID, and a name are associated. Each record (one row of data) in the user information table corresponds to one user information.

  As described above, the user ID is information that identifies a user. The group ID is information that identifies the group to which the user belongs. The name is information indicating the name of the user.

  As an example of a group, a group sharing the same base (for example, a home or a workplace) can be cited. The base will be described later. In this embodiment, the group is a family. That is, if user A and user B are family members, a common group ID is assigned to user A and user B. Further, in the present embodiment, it is assumed that the user is explicitly registered in advance because there is a concern about privacy about which user is given a common group ID. For example, first, the viewer of the mobile terminal 2a makes a request to register that he / she is a family member of the mobile terminal 2b and the user ID of the viewer of the mobile terminal 2a and the viewer of the mobile terminal 2b. It is transmitted to the server 1 together with the user ID. And the server 1 which received the said request | requirement WHEREIN: In the user information table stored in the storage part 10, group ID corresponding to the user ID of the to-be-read person of the portable terminal 2a received, and the viewer of the received portable terminal 2b The same group ID is assigned as the group ID corresponding to the user ID.

  The positioning information receiving unit 11 receives information transmitted from the mobile terminal 2 and acquires positioning information. As described above, since the positioning of the own terminal by the mobile terminal 2 is continuously performed, a plurality of positioning information is acquired. It is assumed that one piece of positioning information relates to one position. The plurality of pieces of positioning information indicate a history of the position of the user of the mobile terminal 2. Hereinafter, a plurality of pieces of positioning information are appropriately referred to as position history information.

  The positioning information receiving unit 11 stores the acquired plurality of positioning information in the position history information table of the storage unit 10. FIG. 4 is a diagram illustrating a table example of the position history information table. As illustrated in FIG. 4, the position history information table stores information in which a user ID, latitude, longitude, and positioning time are associated. Each record in the position history information table corresponds to one piece of positioning information.

  The user ID is a user ID related to the positioning information (user ID transmitted together with the positioning information). The latitude and longitude are the latitude and longitude of the positioning point indicated by the positioning information. The positioning time is the time (date and time) when the positioning point indicated by the positioning information is positioned. The user ID, latitude, longitude, and positioning time are information received from the positioning information receiving unit 11. In addition, when the portable terminal 2 transmits positioning information to the server 1 every time it measures, it is good also considering the time which the positioning information receiving part 11 received as positioning time.

  In the present embodiment, the position history information table of the storage unit 10 stores the position history information of the viewed person based on the information received from the portable terminal 2a owned by the viewed person, and the portable information owned by the viewer. The location history information of the viewer based on the information received from the terminal 2b is stored.

  The base calculation unit 12 calculates a stay point indicating a position where the user stays based on the position history information stored by the storage unit 10. The stay of the user means that the user stays in a narrow area to some extent, that is, the user is continuously located in the predetermined area for a predetermined time or more. The stay point is an area where the user stays or a position representing the area. The site calculation unit 12 calculates a stay point for each user ID. Specifically, the site calculation unit 12 calculates a stay point as follows.

  The site calculation unit 12 acquires the positioning information of the user ID of the calculation target user from the position history information table shown in FIG. All users may be sequentially calculated users, or a specific user set in advance may be the calculation target. Note that the positioning information acquired from the position history information table is set in advance based on the positioning time, for example. Specifically, as described later, the positioning information on the day before the stay point calculation time is acquired.

  The base calculation unit 12 determines the staying point in the order of old positioning time for the acquired positioning information. First, the base calculation unit 12 sets the position indicated by the positioning information with the oldest positioning time as the reference position for determining the staying point. The site calculation unit 12 compares the position where the positioning time is indicated by the next positioning information with the reference position. The site calculation unit 12 determines whether or not the distance between these positions is smaller than a preset distance threshold for determining a staying point. If the base calculation unit 12 determines that the distance is smaller than the distance threshold, the base calculation unit 12 further compares the position indicated in the next positioning information with the reference position, and makes a determination based on the same distance threshold as described above. The site calculation unit 12 sequentially makes a determination until the distance becomes smaller than the distance threshold (the distance becomes equal to or greater than the distance threshold).

  The base calculation unit 12 compares the positioning time related to the previous positioning information whose distance becomes smaller than the distance threshold with the positioning time related to the positioning information of the reference position. The site calculation unit 12 determines whether or not the time difference between these positioning times is larger than a preset time threshold for staying point determination. If the base calculation unit 12 determines that the time difference is larger than the time threshold, the base calculation unit 12 obtains the positioning information (positioning information from the positioning information at the reference position to the previous positioning information whose distance is larger than the distance threshold), It is determined that the positioning information constitutes the stay point. That is, in this case, the site calculation unit 12 determines that the stay point can be extracted. If the base calculation unit 12 determines that the time difference is not larger than the time threshold, the base calculation unit 12 obtains the positioning information (positioning information from the positioning information at the reference position to the previous positioning information whose distance is larger than the distance threshold). , It is determined that the positioning information does not constitute the stay point. That is, in this case, the site calculation unit 12 determines that the stay point cannot be extracted.

  In addition, the base calculation unit 12 performs the same determination as described above using the position indicated by the positioning information whose distance is no smaller than the distance threshold as the reference position for determining a new stay point. Thus, if the user is located in the region from the reference position to the distance threshold for a time exceeding the time threshold, it is determined that there is a staying point. The distance threshold and the time threshold are appropriately set according to the purpose of calculating the stay point. The region for determining the stay point may be a circular region based on the reference position as described above, or a rectangular (mesh) region based on the reference position.

  Subsequently, the base calculation unit 12 calculates the latitude and longitude of the stay point from the positioning information that is supposed to form the stay point. The latitude and longitude of the stay point are positions that represent the stay point, and can be, for example, the center of gravity (average position) of the position indicated by the positioning information that constitutes the stay point. Note that the latitude and longitude of the stay point may be calculated by methods other than this method.

  The site calculation unit 12 stores the stay point information regarding the stay point calculated as described above in the stay point information table of the storage unit 10. FIG. 5 is a diagram illustrating a table example of the stay point information table. As shown in FIG. 5, the staying point information table stores information in which staying point ID, user ID, longitude, latitude, start time, end time, and base ID are associated with each other. Each record (one line of data) in the user staying point information table corresponds to one staying point information.

  The stay point ID is information for specifying the stay point. The staying point ID is given by the storage unit 10 when information is stored in the staying point information table, for example. The user ID is a user ID related to the stay point information. The longitude and latitude are the latitude and longitude of the stay point calculated by the base calculation unit 12 as described above. The start time is the time (date and time) when the stay at the stay point is started, and is the positioning time of the first positioning information among the positioning information that is supposed to form the stay point. The end time is the time when the stay at the stay point is finished, and is the positioning time of the last positioning information among the positioning information that is supposed to form the stay point. As described above, the stay point information table stores the history of the stay point of the user.

  The base calculation unit 12 may calculate a stay point every time positioning information is stored by the positioning information receiving unit 11, or may calculate a stay point periodically (for example, every day at 8 am). The stay point may be calculated when there is an explicit instruction from the administrator of the server 1 or the user of the mobile terminal 2.

  The site calculation unit 12 distinguishes, for each calculated stay point of each user, whether the stay point is in common with another user's stay point belonging to the same group as the user. Here, the fact that a certain user's stay point is in common with another user's stay point indicates, for example, that one user's stay point and another user's stay point are classified into the same cluster by clustering described later. In order to make the above-described distinction, the base calculation unit 12 may share the user's stay point and the other user's stay point when the user's stay point is in common with another user's stay point belonging to the same group as the user. The same base ID is assigned to the stay point. On the other hand, if the user's stay point is not in common with another user's stay point belonging to the same group as the user, the site calculation unit 12 assigns a unique base ID to the user's stay point. A staying point assigned with a base ID is called a base. That is, the base calculation unit 12 calculates a base indicating the position where the user stayed based on the position history information stored by the storage unit 10. More specifically, the site calculation unit 12 indicates the location where the user stays and the location where the viewer stays based on the position history information and the viewer location history information stored by the storage unit 10, respectively. Each viewer base is calculated.

  A specific method for assigning a base ID by the base calculation unit 12 will be described. First, the site calculation unit 12 extracts the stay points of users belonging to the same group from the stay point information table of the storage unit 10. Specifically, the site calculation unit 12 extracts a user ID associated with the group ID for each group ID in the user information table of the storage unit 10, and extracts it from the stay point information table of the storage unit 10. The stay point information of the user ID is extracted. Next, the site calculation unit 12 clusters the latitude and longitude included in the stay point information for each extracted user ID using spatial clustering (for example, MeanShift method), and for each clustered stay point information. Different base IDs will be assigned. That is, the same base ID is assigned to the stay point information in the same cluster, and different base IDs are assigned to the stay point information in different clusters. The site calculation unit 12 assigns the site ID to the stay point information, and simultaneously associates the site ID with the corresponding stay point information in the stay point information table of the storage unit 10. Specifically, in the table example of the stay point information table shown in FIG. 5, the base ID assigned to the stay point information is stored in the rightmost base ID column of the corresponding stay point information.

  The site calculation unit 12 sets (associates) the site type with the assigned site ID. The base type is information indicating what kind of position the staying point information of the user given the base ID is for the user. That is, the base calculation unit 12 sets a specific base (a base where a base type is set) indicating a specific position among the calculated bases. In the present embodiment, three types of “home”, “workplace”, and “other” are used as base types. “Others” is described as “base n” (n is a number). The site calculation unit 12 sets a site type for the site ID assigned to the stay point information based on the stay point information. For example, the base calculation unit 12 includes stay point information that satisfies a predetermined condition in which a start time and an end time are set in advance among stay point information of a user (for example, from 3 am to 4 am in the last 10 days). “Home” is set as the site type for the site ID assigned to the most frequent stay point information). In addition, for example, the base calculation unit 12 includes the stay point information that satisfies a predetermined condition in which the start time and the end time are set in advance among the stay point information of a certain user (for example, 2:00 pm on weekdays of the latest 10 days) “Workplace” is set as the site type for the site ID assigned to the most frequent stay point information between 1 and 3 pm.

  The base type may be explicitly set by the user (viewee). For example, the site calculation unit 12 first transmits the stay point information in which the site ID is stored to the mobile terminal 2. Next, the mobile terminal 2 displays the contents of the received stay point information on the screen of the mobile terminal 2. Next, the user (viewee) of the mobile terminal 2 sets a site type for each site ID based on the displayed information. Note that the user may explicitly set (change) a new site type, such as “kindergarten” or “supermarket”, for the stay point information in which “other” is set as the site type. Next, the user of the portable terminal 2 transmits the information to the server 1 by giving an instruction to transmit the set information to the server 1. Next, the site calculation unit 12 sets the site type based on the received information (updates the staying point information table in the storage unit 10).

  The base calculation unit 12 stores the base information regarding the base for each user including the assigned base ID and the set base type in the base information table of the storage unit 10. FIG. 6 is a diagram illustrating a table example of the base information table. As illustrated in FIG. 6, the site information table stores information in which a user ID, a group ID, a site ID, and a site type are associated. Each record in the site information table corresponds to one site information.

  The user ID is a user ID related to the base information. The group ID is a group ID related to the group to which the user belongs. The base ID is a base ID assigned by the base calculation unit 12. The base type is the base type set by the base calculation unit 12 for the assigned base ID.

  The base information may further include a base address and representative latitude and longitude of the base. After the update of the stay point information table and the base information table in the storage unit 10 is completed, the site calculation unit 12 outputs information indicating the completion of the update to the browsing policy determination unit 13.

  The browsing policy determination unit 13 determines a browsing policy at a position included in the position history information based on the position history information stored by the storage unit 10, and outputs the determined browsing policy. Specifically, the browsing policy determination unit 13 determines the browsing policy at the base calculated by the base calculation unit 12. Further, the browsing policy determination unit 13 calculates a browsing tolerance indicating browsing tolerance, determines a browsing policy based on the calculated browsing tolerance, and sets the determined browsing policy to the calculated browsing tolerance. You may output based on. This will be specifically described below.

  When the browsing policy determination unit 13 acquires the information indicating the completion of the update from the site calculation unit 12, first, based on the stay point information and user information stored by the storage unit 10, the browsing policy determination unit 13 at each site for each user. Base location information on residence is calculated. Specifically, the browsing policy determination unit 13 extracts the user ID, the site ID, the start time, and the end time for each stay point information stored by the storage unit 10 and sets it as the base stay information. Next, the browsing policy determination unit 13 acquires the group ID corresponding to the user ID of the base stay information from the user information stored by the storage unit 10 and further associates the group ID with the base stay information. Then, the browsing policy determination unit 13 stores the calculated base stay information in the base stay information table of the storage unit 10. FIG. 7 is a diagram illustrating a table example of the base residence information table. As shown in FIG. 7, the base residence information table stores information in which a user ID, a group ID, a base ID, a start time, and an end time are associated. Each record (one row of data) in the base stay information table corresponds to one base stay information. The user ID, group ID, base ID, start time, and end time are a user ID, a group ID, a base ID, a start time, and an end time related to the base stay information, respectively.

  Next, the browsing policy determination unit 13 calculates inter-base movement information related to movement between bases for each user based on the staying point information and user information stored by the storage unit 10. The inter-base movement information includes information about the user's source base and the time when the user started moving from the source base, and information about the user's destination base and the time when the user finished moving to the destination base. Is included.

  Specifically, the browsing policy determination unit 13 acquires the base of the user ID of the calculation target user from the stay point information table stored by the storage unit 10. All users may be sequentially calculated users, or a specific user set in advance may be the calculation target. The browsing policy determination unit 13 calculates the inter-base movement information for the acquired bases in the order from the oldest start time as follows. First, the browsing policy determination unit 13 calculates a base with the oldest start time as the base of the movement source, and an end time included in the base as the time when the movement started from the base. Next, the browsing policy determination unit 13 calculates the start time included in the base as the time when the movement to the base ends, with the base having the next start time as the base of the movement destination. The browsing policy determination unit 13 sequentially calculates the inter-base movement information up to the base with the newest start time.

  The browsing policy determination unit 13 stores the calculated inter-base movement information in the inter-base movement information table of the storage unit 10. FIG. 8 is a diagram illustrating a table example of the inter-base movement information table. As shown in FIG. 8, the inter-base movement information table stores information in which a user ID, a group ID, a source base ID, a destination base ID, a start time, and an end time are associated with each other. Each record (one line of data) in the inter-base movement information table corresponds to one inter-base movement information.

  The user ID is a user ID related to the inter-base movement information. The group ID is associated with the user ID stored in the storage unit 10 and is acquired and stored by the browsing policy determination unit 13 when the information is stored in the inter-base movement information table. . The movement source base ID is a base ID indicating the movement source base calculated at the time of calculation by the browsing policy determination unit 13 described above. The movement destination base ID is a base ID indicating the movement destination base calculated at the time of calculation by the browsing policy determination unit 13 described above. The start time is a time at which movement is started from the base, which is calculated at the time of calculation by the browsing policy determination unit 13 described above. The end time is the time when the movement to the base is completed, which is calculated at the time of calculation by the browsing policy determination unit 13 described above.

As described above, the browsing policy determination unit 13 that calculated the base stay information and the inter-base movement information next determines the permissibility of browsing at each base for each user based on the calculated base stay information and the base inter-location movement information. The first index shown is calculated. The higher the value of the first index, the more permissible browsing is, and the more detailed the position information of the person to be viewed that the viewer can browse is. Here, the first index s ₁ (i, k) at the base k of the user i is calculated by the following equation (1).
s ₁ (i, k) = c ₁ · p ₁ (i, k) + c ₂ · p ₂ (i, k) + c ₃ · p ₃ (i, k) (1)
Here, c ₁ , c _2, and c ₃ are predetermined constants set in advance (for example, real numbers of 0 or more), and are set in advance by the administrator of the server 1, for example. In addition, p ₁ (i, k), p ₂ (i, k), and p ₃ (i, k) are represented by the following formulas (2) to (4), respectively.
p ₁ (i, k) = n ₁ (i, k) / n _home (i) (2)
p ₂ (i, k) = n ₂ (i, k) / n _home (i) (3)
p ₃ (i, k) = n ₃ (i, k) / n (4)
Here, n indicates the most recent number of days to be calculated (the number of days going back from the time of calculation according to the formula (1)), and is set in advance by the administrator of the server 1, for example. n _home (i) indicates the cumulative number of days that the user i stayed at the home which is the specific base during the last n days. n ₁ (i, k) indicates the number of days that the user i has moved directly from the specific home to the base k without passing through another base in the last n days. n ₂ (i, k) indicates the number of days that the user i has moved directly from the base k to the home that is the specific base without passing through another base in the last n days. n ₃ (i, k) indicates the number of days that the user i stayed at the base k in the last n days. In the present embodiment, “days” may be replaced with “number of times”. Further, any one or two of c ₁ , c ₂ and c ₃ may be 0. For example, s ₁ (i, k) may be calculated based only on p ₁ (i, k), may be calculated based only on p ₂ (i, k), or p ₃ (i , K) alone.

Hereinafter, a method of calculating n _home (i), n ₁ (i, k), n ₂ (i, k), and n ₃ (i, k) by the browsing policy determination unit 13 will be described.

A method for calculating n _home (i) by the browsing policy determination unit 13 will be described. First, in order to obtain the home base ID, the browsing policy determination unit 13 uses the base ID that indicates the user i in the base information table illustrated in FIG. 6 and the base ID that indicates the home in the base ID. Some base information is extracted, and a base ID associated with the extracted base information is acquired. Next, the browsing policy determination unit 13 uses the built-in function of the server 1 to acquire the current date and time. Next, the browsing policy determination unit 13 in the base residence information table shown in FIG. 7, the user ID is the user ID indicating the user i, the base ID is the home base ID acquired earlier, and the start Base residence information whose time is within n days from the current date and time acquired earlier is extracted. Next, the browsing policy determination unit 13 calculates the sum (excluding duplicates) of dates included in the start time and end time of each base location information extracted, and calculates the calculated total as the value of n _home (i). To do.

Subsequently, a method of calculating n ₁ (i, k) by the browsing policy determination unit 13 will be described. First, in order to obtain the home base ID, the browsing policy determination unit 13 uses the base ID that indicates the user i in the base information table illustrated in FIG. 6 and the base ID that indicates the home in the base ID. Some base information is extracted, and a base ID associated with the extracted base information is acquired. Next, the browsing policy determination unit 13 uses the built-in function of the server 1 to acquire the current date and time. Next, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 is a user ID indicating the user i, and the source base ID is the home base ID acquired earlier, And the movement destination base ID is the base ID of the base k, and the inter-base movement information whose start time is within n days from the current date and time acquired earlier is extracted. Next, the browsing policy determination unit 13 calculates the sum of dates (excluding duplication) included in the start time and end time of the extracted inter-base movement information, and calculates the calculated sum as a value of n ₁ (i, k). Calculate as

Subsequently, a calculation method of n ₂ (i, k) by the browsing policy determination unit 13 will be described. First, in order to obtain the home base ID, the browsing policy determination unit 13 uses the base ID that indicates the user i in the base information table illustrated in FIG. 6 and the base ID that indicates the home in the base ID. Some base information is extracted, and a base ID associated with the extracted base information is acquired. Next, the browsing policy determination unit 13 uses the built-in function of the server 1 to acquire the current date and time. Next, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 has the user ID as the user ID indicating the user i, the source base ID is the base ID of the base k, and The movement destination base ID is the home base ID acquired earlier, and the movement information between bases whose start time is within n days from the current date and time acquired earlier is extracted. Next, the browsing policy determination unit 13 calculates the sum (excluding duplicates) of dates included in the start time and end time of the extracted inter-base movement information, and calculates the calculated sum as a value of n ₂ (i, k). Calculate as

Subsequently, a method of calculating n ₃ (i, k) by the browsing policy determination unit 13 will be described. The browsing policy determination unit 13 first acquires the current date and time using the built-in function of the server 1. Next, the browsing policy determination unit 13 uses the base ID information table shown in FIG. 7, the user ID is the user ID indicating the user i, the base ID is the base ID of the base k, and the start time is Base residence information that is within n days from the current date and time acquired earlier is extracted. Next, the browsing policy determination unit 13 calculates the sum (excluding duplication) of the dates included in the start time and end time of each extracted base residence information, and calculates the calculated sum as a value of n ₃ (i, k). Calculate as

  The browsing policy determination unit 13 stores the calculated first index for each base of each user in the first index information table of the storage unit 10 as first index information. FIG. 9 is a diagram illustrating a table example of the first index information table. As illustrated in FIG. 9, the first index information table stores information in which the user ID to be browsed, the group ID, the base ID, and the first index score are associated with each other. Each record in the first index information table corresponds to one first index information.

  The viewed user ID is the user ID of the user (user i in the above calculation) related to the first index information. The group ID is the group ID of the user. The base ID is the base ID of the base (the base k in the above calculation) related to the first index information. The first index score is a score (value) of the first index calculated by Expression (1).

  Subsequently, the browsing policy determination unit 13 determines a browsing policy based on the calculated first index and a threshold value for browsing availability. FIG. 10 is a diagram illustrating a table example of a browseability information table of browseability information regarding a browseability threshold. As illustrated in FIG. 10, the browsing availability information table stores information in which a policy ID, a score threshold, a browsing policy, and details are associated with each other. Each record in the viewability information table corresponds to one viewability information.

  The policy ID is information that specifies browsing permission / inhibition information. The score threshold value is a threshold value of the score of the first index. If the score of a 1st parameter | index is more than the said threshold value, the below-mentioned browsing policy will be applied. The browsing policy indicates the details of the location information of the browser that is disclosed to the viewer. For example, “is in the place” as an example shown in FIG. 10 indicates whether or not the location is pinpointed (for example, the person being viewed is within a radius of 100 m centered on the latitude and longitude indicating the location). Indicates that it will be made public. Further, “Nearby” as an example shown in FIG. 10 indicates whether or not the person is near the base (for example, whether the person being viewed is within a radius of 1 km centered on the latitude and longitude indicating the base). Indicates. Details are text that describes the details of the browsing policy. If the score of the first index is less than all score threshold values of the browsing availability information included in the browsing availability information table (less than 0.3 in the example of the browsing availability information table shown in FIG. 10), browsing is permitted. Not.

  When the browsing policy determining unit 13 determines a browsing policy for each base of a certain person to be browsed, first, the first index in which the user ID of the person to be viewed is associated from the first index information table illustrated in FIG. Extract information. Next, the browsing policy determination unit 13 compares the first index score associated with each base ID associated with the extracted first index information with the score threshold of the browsing availability information table illustrated in FIG. Browseability information that is equal to or less than one index score and is associated with the maximum score threshold in the viewability information table is extracted. The browsing policy associated with the extracted browsing permission information is the browsing policy of the base indicated by the base ID. As described above, the browsing policy determination unit 13 determines a browsing policy for each base.

  FIG. 11 is a diagram illustrating a screen output example of the browsing policy determined by the browsing policy determination unit 13. In the screen output example shown in FIG. 11, the output instruction output by the browsing policy determination unit 13 is transmitted to the mobile terminal 2 (of the person to be viewed) and displayed on the screen of the mobile terminal 2 based on the output instruction. It is. The output instruction includes, for example, information indicating a base, a first index score of the base, and information indicating a browsing policy calculated for the base. As in the screen output example shown in FIG. 11, the mobile terminal 2 can drag and drop information indicating a base where the browsing policy is set in the corresponding section R for each browsing policy included in the output instruction. Display as a new area D. The reason for displaying as a region D that can be dragged and dropped is that the user (viewee) of the mobile terminal 2 drags and drops the region D into another section R, so that the browsing policy of the base corresponding to the region D is set. This is because the browsing policy corresponding to the dropped section R can be changed. Further, in the screen output example shown in FIG. 11, the user (viewee) of the mobile terminal 2 selects the link “confirm on map” in the area D, so that the position of the corresponding base is displayed on another screen or the like. It can be confirmed on the displayed map. In addition, when displaying the information which shows the base, the portable terminal 2 displays it in order with the big 1st index score matched with the said base.

  The above is the description of the process for determining the browsing policy for each base of the person to be browsed by the browsing policy determination unit 13. Next, a process of determining a browsing policy for each viewer and each site by the browsing policy determination unit 13 will be described.

  The browsing policy determination unit 13 determines a browsing policy for the viewer at the position included in the location history information based on the location history information stored in the storage unit 10 and the viewer location history information of the viewer. Specifically, the browsing policy determination unit 13 includes the position history information stored in the storage unit 10 and the viewer's browser location history information, the base calculated by the base calculation unit 12, and the viewer's base of the viewer. Based on the above, the browsing policy for the viewer at the base is determined. This will be specifically described below.

The browsing policy determination unit 13 calculates a second index indicating the permissible browsing for each base for the viewer of the viewer based on the calculated base stay information and inter-base movement information. Here, the 2nd index | index for every base k with respect to the browsing person j of the to-be-viewed person i is calculated by the following formula | equation (5).
s ₂ (i, j, k) = c ₄ · p ₄ (i, j, k) + c ₅ · p ₅ (i, j, k) (5)
Here, c ₄ and c ₅ are predetermined constants (for example, real numbers greater than or equal to 0) set in advance, and are set in advance by the administrator of the server 1, for example. Further, p ₄ (i, j, k) and p ₅ (i, j, k) are represented by the following equations (6) and (7), respectively.
p ₄ (i, j, k) = n ₄ (i, j, k) / n (6)
p ₅ (i, j, k) = {Σ _l n ₅ (i, j, k, l) + Σ _l n ₅ (i, j, l, k)} / n (7)
Here, n indicates the most recent number of days to be calculated (the number of days going back from the time when the calculation according to Expression (5) is performed), and is set in advance by the administrator of the server 1, for example. n ₄ (i, j, k) indicates the number of days that the user i and the viewer j stay together at the base k. n ₅ (i, j, k, l) indicates the number of times that the person to be viewed i and the viewer j have moved together from the base k to an arbitrary base l, and similarly, n ₅ (i, j, l, k) indicates the number of times that the viewer i and the viewer j have moved from any base l to the base k together. That is, Σ _l n ₅ (i, j, k, l) + Σ _l n ₅ (i, j, l, k) is transferred from the base k to another base together with the viewer i and the viewer j. It means the total of the number of times of movement and the number of times of moving from a certain base to the base k. Note that one of c ₄ and c ₅ may be 0. For example, s ₂ (i, k) may be calculated based only on p ₄ (i, j, k), or may be calculated based only on p ₅ (i, j, k).

Hereinafter, a method of calculating n ₄ (i, j, k), n ₅ (i, j, k, l) and n ₅ (i, j, l, k) by the browsing policy determination unit 13 will be described.

A method for calculating n ₄ (i, j, k) by the browsing policy determination unit 13 will be described. First, the browsing policy determination unit 13 is the base where the user ID is the user ID indicating the person i to be viewed and the base ID is the base k in the base stay information table shown in FIG. Base residence information that is an ID (hereinafter referred to as browse user residence information) is extracted. Next, the browsing policy determination unit 13 has the base residence information (in the base residence information table shown in FIG. 7) where the user ID is the user ID indicating the viewer j and the base ID is the base ID indicating the base k. (Hereinafter referred to as browser base residence information) is extracted. Next, the browsing policy determination unit 13 compares the start time and end time associated with the browsed person base residence information with the start time and end time associated with the browser base residence information, and has overlapped. The time (the time during which the viewer i and the viewer j are together at the base k) is calculated, and the calculated number of days is calculated as the value of n ₄ (i, j, k).

Subsequently, a calculation method of n ₅ (i, j, k, l) by the browsing policy determination unit 13 will be described. First, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 has a user ID whose user ID is the person to be viewed i and whose movement source base ID is the base k. Hereinafter, it is referred to as movement information between browsed person bases). Next, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 is the inter-base movement information (the user ID is the user ID indicating the viewer j and the source base ID is the base k) ( (Hereinafter referred to as inter-browser location information). Next, the browsing policy determination unit 13 compares the movement information between the read person bases and the movement information between the viewer bases, the movement destination base IDs are the same, and the start times are almost the same (within a predetermined time difference). ) And the end times are almost the same (within a predetermined time difference) (the number of times that the viewed person i and the viewer j have moved together from the base k to the base indicated by the destination base ID) Is calculated as the value of n ₅ (i, j, k, l).

Next, a method for calculating n ₅ (i, j, l, k) by the browsing policy determination unit 13 will be described. First, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 has a user ID whose user ID is a user ID indicating the person i to be viewed and whose movement destination base ID is the base k ( Hereinafter, it is referred to as movement information between browsed person bases). Next, in the inter-base movement information table shown in FIG. 8, the browsing policy determination unit 13 is the inter-base movement information (the user ID is the user ID indicating the viewer j and the destination base ID is the base k) ( (Hereinafter referred to as inter-browser location information). Next, the browsing policy determination unit 13 compares the movement information between the browsing target bases and the movement information between the browsing bases, the source base IDs are the same, and the start times are almost the same (within a predetermined time difference). ) And the end times are almost the same (within a predetermined time difference) (the number of times the viewed person i and the viewer j have moved together from the base indicated by the source base ID to the base k) Is calculated as the value of n ₅ (i, j, l, k).

  The browsing policy determining unit 13 stores the calculated second index for each base for each viewer of each viewed person as second index information in the second index information table of the storage unit 10. FIG. 12 is a diagram illustrating a table example of the second index information table. As illustrated in FIG. 12, the second index information table stores information in which the browse user ID, the browse user ID, the group ID, the base ID, and the second index score are associated with each other. Each record in the second index information table corresponds to one second index information.

  The viewed user ID is the user ID of the viewed person (the viewed person i in the above calculation) according to the second index information. The browser user ID is the user ID of the viewer (the viewer j in the above calculation) related to the second index information. The group ID is the group ID of the viewer and the viewer. The base ID is a base ID of a base related to the second index information (base k in the above calculation). The second index score is the score (value) of the second index calculated by Expression (5).

  Subsequently, the browsing policy determination unit 13 determines a browsing policy based on the calculated second index and a threshold value for browsing availability. The determination method using the browseability information is the same as the determination method for the first index described above (the determination method for the second index is further determined for each person to be viewed), and thus the description thereof is omitted.

  FIG. 13 is a diagram illustrating a screen output example of the browsing policy determined by the browsing policy determination unit 13. In the screen output example shown in FIG. 13, the output instruction output by the browsing policy determination unit 13 is transmitted to the mobile terminal 2a of the person to be viewed, and is displayed on the screen of the mobile terminal 2a based on the output instruction. . The output instruction includes, for example, information indicating the person to be viewed, information indicating the viewer, information indicating the base, the second index score of the base, and information indicating the browsing policy calculated for the base. As in the screen output example shown in FIG. 13, the mobile terminal 2 a is for each viewer included in the output instruction (“Mr. XX displayed at the top of the screen output example indicates the name of the viewer)” For each browsing policy, information indicating the base where the browsing policy is set in the corresponding section R is displayed as an area D that can be dragged and dropped. The reason for displaying as a region D that can be dragged and dropped is that the user who is the user of the portable terminal 2a drags and drops the region D into another section R, so that the browsing policy of the base corresponding to the region D is set. This is because the browsing policy corresponding to the dropped section R can be changed. Further, in the screen output example shown in FIG. 13, the viewer can select the link “confirm on map” in area D to confirm the position of the corresponding base on the map displayed on another screen or the like. can do. In addition, when displaying the information which shows the base, the portable terminal 2a displays it in order with the 2nd large index score matched with the said base. In addition, as shown in the screen output example shown in FIG. 13, when a viewer selects a “previous person” or “next person” that is a selectable link L, it is set for another viewer. You can check your browsing policy.

  The above is the description of the process by which the browsing policy determination unit 13 determines the browsing policy for each base for the viewer of the viewer.

In the example of calculating the browsing policy using the second index, a comprehensive index described below may be used instead of the second index. The comprehensive index s ₃ (i, j, k) is calculated by the following equation (8).
_{s 3 (i, j, k} ) = c 6 · s 1 (i, k) + c 7 · s 2 (i, j, k) ··· (8)
Here, c ₆ and c ₇ are predetermined constants (for example, real numbers greater than or equal to 0) that are set in advance, for example, set by the administrator of the server 1 in advance. Further, s ₁ (i, k) is a first index calculated as described above, and s ₂ (i, k, k) is a second index calculated as described above. That is, the browsing policy determination unit 13 may determine the browsing policy based on the first index and the second index.

  When the browsing policy determination unit 13 determines the browsing policy using the comprehensive index, the calculated total index for each base for each viewer of each browsed person is calculated as the total index information, similarly to the second index information described above. Is stored in the general index information table of the storage unit 10. FIG. 14 is a diagram illustrating a table example of the comprehensive index information table. As illustrated in FIG. 14, the comprehensive index information table stores information in which a browse user ID, a browse user ID, a group ID, a base ID, a comprehensive index score, and a user manual input policy ID are associated with each other. Each record in the comprehensive index information table corresponds to one comprehensive index information.

  Since the browsing user ID, the browsing user ID, the group ID, and the base ID are the same as the second index information, description thereof is omitted. The total index score is a score (value) of the total index calculated by Expression (8). The user manual input policy ID will be described later.

  The browsing policy manual setting unit 14 sets contents manually changed by the user for the browsing policy determined by the browsing policy determination unit 13. For example, in the screen output example shown in FIG. 11 or FIG. 13, a description will be given of a method in which the user manually changes the base “home” set to the browsing policy “is in the place” to the browsing policy “near”. To do. First, the user drags the area “home” set in the section “I am at the place” to the subordinate of the section “near” (the place where the area “base 2” and the area “base 3” are arranged). & Drop. Then, the mobile terminal 2 transmits to the server 1 information indicating that the browsing policy of the base “home” has been changed from “I am at that place” to “I am near”. Then, the browsing policy manual setting unit 14 of the server 1 receives the information, and changes the browsing policy of the base “home” determined by the browsing policy determination unit 13 from “I am in that place” to “I am near”. . For example, in the comprehensive index information table shown in FIG. 14, as the user manual input policy ID of the comprehensive index information corresponding to the “home”, the policy corresponding to the browsing policy “near” in the browsing availability information table shown in FIG. Associate ID. For the comprehensive index information associated with the user manual input policy ID, the browsing policy based on the total index score is ignored, and processing is performed assuming that the browsing policy indicated by the user manual input policy ID is set.

  The browsing request processing unit 15 receives a browsing request for the location information of a specific viewer from the mobile terminal 2b of the viewer, and carries the location information of the viewer based on the browsing policy of the viewer. Provided to the terminal 2b. The position information to be provided is information indicating where the user of the mobile terminal 2a is now and where the user is. The location information may be the name of the base type ("Home", "Workplace", "Kindergarten", "Super", etc.), or more detailed location information such as the latitude and longitude of the base. There may be.

  Next, processing of the browsing policy determination method in the server 1 according to the present embodiment will be described using the flowcharts shown in FIGS. 15 and 16. First, the process of determining the user's browsing policy based on the first index will be described using the flowchart shown in FIG.

  First, the base calculation unit 12 calculates the staying point of the user based on the user's position history information (step S1), and calculates the base based on the calculated staying point (step S2). Next, the browsing policy determination unit 13 calculates a first index based on the position history information and the base (step S3), and determines and outputs a browsing policy based on the calculated first index (step S4). ).

  Next, a process of determining a browsing policy for each viewer of the viewer based on the comprehensive index will be described using the flowchart shown in FIG.

  First, the base calculation unit 12 calculates the staying points of the viewer and the viewer based on the location history information of the viewer and the viewer (step S10). Based on each staying point of the viewer, the bases of the viewer and the viewer are calculated (step S11). Next, the browsing policy determination unit 13 calculates the first index and the second index based on the location history information and the bases of the viewer and the viewer, and calculates the calculated first index and second index. A comprehensive index is calculated based on the calculated index (step S12), and a browsing policy is determined and output based on the calculated total index (step S13).

In the present embodiment, the group is a family and the browsing policy within the family has been described. However, the present invention is not limited to this. For example, the group may be a colleague at work, and the server 1 may determine and calculate a browsing policy within the work colleague. In this case, n _home (i) in this embodiment is replaced with n _office (i), which is the cumulative number of days that user i has stayed at the workplace for the last n days, and performs the same determination and calculation.

  Next, the operation and effect of the server 1 configured as in the present embodiment will be described.

  According to the server 1 of this embodiment, a browsing policy is determined based on position history information. That is, the browsing policy can be determined based on the history of the position of the user (or the mobile terminal 2) without the user performing a special operation. That is, it is possible to further reduce the burden on the user and determine the browsing policy.

  Moreover, according to the server 1 of this embodiment, the browsing policy in the base which shows the position where the user (or portable terminal 2) stayed can be determined.

  Further, according to the server 1 of the present embodiment, the number of times that the user (or the mobile terminal 2) has moved directly from the specific base to the one base and the user (or the mobile terminal 2) has moved directly from the one base to the specific base. The browsing policy is determined based on at least one of the number of times. For example, when a specific base is a home, the location information of one base that has been moved frequently from the home and one base that has been moved directly to the home is equivalent to the user's daily behavior and is confidential. Therefore, there is a high possibility that there will be no problem for the user even if it is viewed. Therefore, for example, as the number of times increases, a browsing policy that is more problematic for the user can be determined by deciding the browsing policy so that the restriction on browsing with respect to the position information of the user (or the mobile terminal 2) at the one base is relaxed. Can be determined.

  Generally, there is a high possibility that the position information of one base where the user (or the mobile terminal 2) stayed has a long problem even if viewed. That is, according to the server 1 of the present embodiment, for example, as the time is longer, the viewing policy is determined so that the viewing restriction on the position information of the user (or the mobile terminal 2) at the one base is loosened. Thus, it is possible to determine a browsing policy that is more problematic for the user.

  Moreover, according to the server 1 of this embodiment, the browsing policy of the viewer with respect to the location information of the user (or the mobile terminal 2a) is the location history information of the user (or the mobile terminal 2a) and the viewer (or mobile phone). Since it is determined based on the viewer location history information of the terminal 2b), for example, the viewer based on the similarity of the behavior (or movement) of the user (or the mobile terminal 2a) and the viewer (or the mobile terminal 2b) The browsing policy can be determined.

  Moreover, according to the server 1 of this embodiment, the browsing policy of the viewer in the base which shows the position where the user (or portable terminal 2a) stayed can be determined. In addition, the browsing policy includes the location history information of the user (or mobile terminal 2a) and the viewer location history information of the viewer (or mobile terminal 2b), the base of the user (or mobile terminal 2a), and the viewer (or mobile phone). Since it is determined based on the viewer base of the terminal 2b), for example, the browsing is based on the similarity of the behavior (or movement) of the base of the user (or mobile terminal 2a) and the viewer (or mobile terminal 2b). The browsing policy of the person can be determined.

  In general, the location information of one base where the user (or the mobile terminal 2a) and the viewer (or the mobile terminal 2b) have stayed together may have no problem for the user even if the location information is viewed by the viewer. High nature. That is, according to the server 1 of the present embodiment, for example, as the time is longer, the viewing policy is configured so that the restriction on the browsing of the viewer with respect to the position information of the user (or the mobile terminal 2a) at the one base is relaxed. By determining, it is possible to determine a browsing policy that is more problematic for the user.

  In general, the number of times that the user (or mobile terminal 2a) and the viewer (or mobile terminal 2b) have moved together from one base to another base and the user (or mobile terminal 2a) and the viewer (or mobile terminal 2b) ) Is more likely to cause no problem for the user even if the position information of the one base is viewed by the viewer, as the number of times of movement to the one base from the other base increases. That is, according to the server 1 of the present embodiment, as the number of times increases, the browsing policy is determined so that the viewer's browsing restriction on the position information of the user (or the mobile terminal 2a) at the one base is loosened. By doing so, it is possible to determine a browsing policy that is more problematic for the user.

  Further, according to the server 1 of the present embodiment, for example, for the user, the position information having a higher viewing allowance is displayed at a higher position, and the position information having a lower viewing allowance is displayed at a lower position. You can intuitively understand the permissible viewing of each piece of information.

  As described above, according to the server 1 of the present embodiment, it is possible to automatically set a browsing policy regarding sharing of location information such as “who (which device) is now” in the same group. For example, if location information can be shared among a limited number of users such as family members, for example, who will do some work (shopping) with a family view, preparations that pre-read someone's actions (for example, husband's return home) Useful for housework that meets expectations). And according to the server 1 of this embodiment, a browsing policy can be determined based on the depth (1st parameter | index) of a user (or portable terminal 2) and main bases, such as a house. Thereby, it is possible to automatically determine a browsing policy that is less problematic for the user, and to reduce the burden of setting the browsing policy for the user. Further, according to the server 1 of the present embodiment, the similarity (second index, comprehensive index) of the behavior (or movement) between the viewer (or mobile terminal 2a) and the viewer (or mobile terminal 2b) is also achieved. In addition, a browsing policy can be determined based on. Thereby, it is possible to automatically determine a browsing policy that is more problematic for the viewer, and to reduce the burden of the browsing policy setting of the viewer.
